DETAILED DESCRIPTION OF THE DISCLOSURE

As shown in FIGS. 1 to 2 , the turbine fracturing system above (including one or more of the various driving, transmission, speed reduction and other components) may include a soundproof cabin for the turbine engine. The soundproof cabin may be sleeved on the turbine engine 7. The soundproof cabin may include a cabin body, an induction noise reduction unit and a ventilation noise reduction unit. The induction noise reduction unit and the ventilation noise reduction unit may be disposed on the cabin body. The surrounding of the cabin body frame may be filled with soundproof materials. The induction noise reduction unit may be used to reduce the induction noise of the turbine engine 7. The ventilation noise reduction unit may be used to reduce the noise of the ventilation system of the turbine engine 7. The soundproof materials may include but are not limited to glass fiber cotton, rock wool, polyurethane, aluminum honeycomb panels, peak type cotton, etc.

The induction noise reduction unit may include an intake filter 6, an intake silencer 5, an intake chamber 2 and an intake piping. The intake chamber 2 may be disposed on the top of the cabin body. The intake filter 6 may be arranged on the outer side face of the intake chamber 2, and the intake silencer 5 may be arranged on the inner side face of the intake chamber 2, with the position of the intake filter 6 corresponding to that of the intake silencer 5. The bottom of the intake chamber 2 may be provided with an air outlet, through which the intake chamber 2 is connected to one end of the intake piping. The other end of the intake piping may be connected to an air inlet of the turbine engine 7. Both the top and bottom surfaces of the intake chamber 2 may be filled with soundproof materials. As shown in FIG. 1 , the induction noise reduction unit or the intake chamber may be configured in the power transmission of the turbine power transmission direction (or axial direction) to cover the entire length of the turbine engine and also cover the end frames (in the power transmission direction) of the cabin body, when viewed from the top. Likewise, as shown in FIG. 1 , the induction noise reduction unit or the intake chamber may be configured in a direction perpendicular power transmission of the turbine power transmission direction (or axial direction) in the horizontal plane to cover the entire width of the turbine engine and also at least cover or extend over the end frames (in the direction perpendicular to the power transmission direction) of the cabin body, when viewed from the top. In other words, in a top view, the induction noise reduction unit or the intake chamber at least covers a peripheral boundary of the cabin body.

There may be no intake filters 6 and intake silencers 5 arranged at the exhaust end of the turbine engine 7. The exhaust end refers to the end at which the exhaust duct 10 of the turbine engine 7 is disposed. The side face of the intake chamber 2 at the side of the exhaust end can also be filled with soundproof materials.

The ventilation noise reduction unit may include an inlet air silencer 4, an inlet air fan and an outlet air silencer 1, wherein the inlet air silencer 4 is connected to the inlet air fan. The inlet air silencer 4, the inlet air fan and the outlet air silencer 1 may be disposed on the cabin body. The inlet air silencer 4 and the outlet air silencer 1 may be arranged on opposite sides of the cabin body.

There may be one or more sets of ventilation noise reduction units. For example, either side of the transmission direction of the turbine engine 7 can be provided with a set of ventilation noise reduction units. Likewise, there may be one, two or more outlet air silencers 1 in each set of ventilation noise reduction unit, thus better effectuating ventilation and noise reduction.

The turbine engine 7 may be further provided with a soundproof door 3 in non-transmission direction, which may be filled with soundproof materials. There may be multiple soundproof doors 3. The multiple soundproof doors filled with soundproof materials may be used for noise insulation of the turbine engine 7 in non-transmission direction, and also offer convenience for repair and daily maintenance.

Operating Principle:

The air used for combustion in the turbine engine 7 is fed through the intake filter 6, enters the intake chamber 2 through the intake silencer 5, and then enters the air inlet of the turbine engine 7 through the intake piping.

The air used for ventilation and cooling in the turbine engine 7 may be fed, under the action of the inlet air fan, into the soundproof cabin of the engine through the inlet air silencer 4, and then discharged to the outside of the soundproof cabin of the engine through the outlet air silencer 1.
